Microsoft has released its second build for Windows Insiders this week for PC and phone, bringing fast ring users up to build 14372, one up from yesterday’s release. Considering this build is only one newer, and we’re almost done with development of the Anniversary Update, this build includes no new features, but lots of bug fixes and other improvements.
We have changed the backup format for Windows 10 Mobile devices to reduce the size of the backup stored in OneDrive. As a result, if you do a backup on a device running the latest Windows 10 Mobile Insider Preview builds and move back to the released version of Windows 10 Mobile (Build 10586) and restore from your backup – your Start screen layout won’t restore and remain the default Start layout. Your previous backup also gets overwritten. If you need to go back to Build 10586
temporarily, once you are on Build 10586 you should disable backup so it doesn’t overwrite the good backup from Windows 10 Mobile Insider Preview builds.
We’ve heard you and we are investigating decreases in battery life on older devices such as the Lumia 830, 930, and 1520 (devices with SoC 8974 chipsets).
We’re investigating Wi-Fi disconnect issues – if you are experiencing an issue with your Wi-Fi disconnecting, please see this forum post and make sure to upvote Wi-Fi disconnecting issues in the Feedback Hub.
